INVENTOR. LARRY N. LANC ASTER BACKGROUND OF THE INVENTION Duringspinning, twisting, or otherwise handling of a textile yarn, yarn isuniformly deposited around a yarn carrier received on a rotatingspindle. It is quite important that the spindle be properly positionedto enable placement of the yarn on the carrier as desired to produce apredetermined shape for the yarn package, to prevent the yarn from beingfrayed and the like. As the spindle rotates, a ring surrounding thespindle traverses a predetermined length of the spindle, being carriedby a traverse rail. Yarn thus passes through a yarn traveler thattravels around the ring and is deposited onto a portion of the carrieradjacent the ring. The spindle should thus be plumb (perpendicular tothe traverse rail and centrally located within the ring surroundingsame).

Historically, spindle plumbing has required a considerable amount oftime and effort. Labor costs have been high and the machines have beenheld out of production for long periods of time. Such plumbing hasgenerally been conducted by loosening the spindle at a point beneath aspindle support rail and adjusting the spindle by trial and error, usingeyesight to determine proper spindle location. Additionally, spiritlevels, plastics discs, and the like have been used, but without therealization of any real improvement, either in time or accuracy. Theindividual would thus use an available device, if any, and determine byeyesight whether the spindle was properly centered in the ring and thusperpendicular to the traverse rail. Such spindle plumbing has led toproblems. A spindle that is out of plumb by only a few thousandths of aninch can cause the building of an improper yarn package and/or themanufacture of second quality yarn due to abrasion of the yarn fromcontact with the traverse rail. This frayed yarn is not visible to thenaked eye and does not show up until woven into a fabric and the fabricdyed or finished.

Once a spindle was adjusted to the proper position, if necessary,precision paper was used to wedge or shim the spindle in this position,after which the spindle was then tightened against the spindle supportrail, and the machine returned to operation. Heretofore, spindles havebeen plumbed idle. Since the plumb of the spindle can change when thespindle rotates, and since the rotating spindle is more nearly at actualconditions, plumbing of the idle spindle is not an optimum operation.There has been no means before now, however, for plumbing a spindlewhile the spindle is rotating.

The device manufactured according to the teachings of the presentinvention can now be used to overcome the disadvantages of the priorart. Not only can a spindle now be plumbed while idle and whilerotating, but also a precision instrument is available to remove themajority of the human error due to inaccurate sighting of the device.Moreover, whereas, it has been previously necessary to strike thespindle with a hammer or other suitable tool to initially approach aplumb position, the device of the present invention automatically forcesthe spindle into approximate plumb, within a few thousandths of an inch,after which a precision indicator may be used to finalize plumbing ofthe spindle. Use of the device according to the teachings of the presentinvention thus reduces the time required to plumb a spindle, permitsbetter plumbing accuracy, and enables the manufacture of a proper yarnpackage while reducing the production of second quality yarn.

The prior art is deficient in teaching or suggesting the device of thepresent invention. Exemplary of the prior art are U. S. Pat. Nos.686,975 to Kelly; 2,240,337 to Lannen; 2,356,311 to Geier and 2,856,696to Williams.

SUMMARY OF THE INVENTION It is an object of the present invention toprovide a device for plumbing a vertical spindle on a textile machine.

A further object of the present invention is to provide an improveddevice for plumbing a rotating vertical spindle on a textile machine.

Still further, another object of the present invention is to provide animproved device for precisely adjusting a vertical spindle on a textilemachine without the necessity of a trial and error eyesight evaluationof the position of the spindle.

Generally speaking, the device of the present invention comprises anelongated cylindrical member having a longitudinal bore therein, saidmember being adapted to reside over a vertical spindle, a verticallyadjustable collar received around said elongated member, said collarhaving an initial spindle adjustment means thereon for engagement with aring surrounding said spindle; and an adjustable indicator meansassociated with said elongated member for vertical and horizontaladjustment with respect thereto, said indicator means being movablearound said spindle to determine whether said spindle is perpendicular'to said rail and located in the center of said ring.

More specifically, the basic device of the present invention includes anelongated member having a longitudinal bore therein that snugly fitsaround a spindle. An adjustable collar having at least one pin typemember extending outwardly therefrom in an axial manner engages the ringof the traverse rail which forces the loosened spindle to move towardsthe center of the ring as the collar is rotated around the ring.Depending upon the particular accuracy and placement of the pin typemember, the spindle can be brought within a small number of thousandthsof an inch of accurate plumb. Thereafter, the adjustable indicator meanshaving a feeler member for engagement with said ring may be moved alongthe length of the spindle to the desired position as is indicated by theparticular placement of the rail and can be rotated around the rail. Asthe indicator is moved around the ring, a feeler riding on the ring willindicate any position in which the spindle is out of plumb, themagnitude of deviation and the direction. After detecting such acondition, the spindle can be tapped very lightly in the appropriatedirection until accurate adjustment is realized.

As mentioned earlier, a device manufactured according to the presentinvention may be successfully used to plumb a spindle while the spindleis rotating. A bearing surface is placed within the longitudinal bore ofthe elongated member and secured therein. The spindle then fits snuglywithin a central tubular member or rail of the bearing which is providedwith roller members. The spindle and tubular member can thus rotatewhile the remainder of the device is held against rotation. Anadjustable stop received on the elongated member engages the nextadjacent spindle and prevents the device from rotating along with therotating spindle being plumbed. The spindle can now be plumbed whilerotating, by use of the device as explained herein. Optionally, thecollar or collars received around the elongated member can have bearingsthereon to permit independent rotation of the collars with respect tothe elongated cylindrical member. Hence with the spindle rotating andthe elongated member being held against rotation by the stop means, thecollars may be independently rotated around the elongated member toplumb the spindle.

A further feature of the present invention is the op tional addition ofa spirit level at the top of the elongated member. This feature has perse, been presented in the prior art. The level addition to the device ofthe present invention, however, is not the primary adjustment means, butis used merely as a means to quickly check accuracy of the spindleplumbing accomplished by the initial adjustment means and the indicator.The spirit level may be used on any embodiment of a device according tothe teachings of the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the Figures of thedrawings, the preferred specific embodiments of the present inventionwill now be described in detail. In FIG. 1, there is shown a portion ofa textile machine such as a spinning machine, twister or the like havinga spindle support rail on which is rotatably supported a spindlegenerally indicated as 20 and a traverse rail 30 that normally traversesup and down a predetermined length of spindle 20 permitting yarn to beplaced on a textile carrier (not shown) that is received on spindle 20.A textile machine such as the type being discussed would normally have alarge number of such spindles extending along the length thereof. A ring32 is shown on traverse rail 30 and surrounding a body 22 of spindle 20.Yarn thus passes through a traveler (not shown) that is received on androtates around ring 32, and is deposited onto a textile carrier. It isquite desirable to produce a yarn package as uniform as possible andalso to provide yarn that has not been adversely affected. In so doing,the vertical spindle should be as close to perpendicular as possiblewith respect to traverse rail 30 and also should be positioned in theprecise center of ring 32 which surrounds spindle 20. Spindle 20 isgenerally rotatably supported by a spindle support assembly generallyindicated as 15 which secures spindle 20 to rail 10 at the properattitude when tightened thereagainst by one or more of nuts 16, 17 and18. A whorl 19 is also provided at the base of spindle 20 to providehigh speed rotation thereto by the passage of a belt or the like (notshown) therearound.

On a periodic basis, it is necessary for the spindles being used on thetextile machine to be adjusted as described above. At such time, thespindle support assembly 15 is slightly loosened from rail 10 and thespindle 20 can now be adjusted. After adjustment, spindle supportassembly 15 is again tightened against rail 10 to maintain the newadjustment.

The device of the present invention is used to adjust the loosenedspindle 20 and comprises an elongated cylindrical member 40 having aconcentric longitudinal bore 41 extending therein. In the embodimentshown in FIG. 1, the spindle body 22 is illustrated extending upwardlyinto bore 41 of elongated cylindrical member 40 and residing snuglytherein. An adjustable collar or clamp 42 is provided around cylindricalmember 40 and held thereon by a bolt 43 or other suitable locking meansso as to permit collar 42 to be securely held at a particular positionalong cylindrical member 40, or when loosened, to be moved along tubularmember 40 and secured again as desired. Collar 42 has a pin 44 extendingdownwardly therefrom. Pin 44 is representative of an initial adjustmentmember that is used to force spindle body 22 to approximately thecentral portion of ring 32 of traverse rail 30. Hence with the spindlesupport assembly 15 slightly loosened to the point where spindle 20 maybe moved laterally, pin 44 is brought to reside within the internaldiameter 32' of ring 32 and may rotate therearound. As pin 44 is rotatedaround the internal diameter 32' of ring 32, spindle 20 is moved towardthe central location within the ring 32. The accuracy of movement ofspindle 20 by collar 42 and pin 44 is dependent upon the accuracy ofplacement of pin 44. It should further be pointed out that a pluralityof pins 44 can be provided around the circumference of collar 42 or thatother structural members can be provided so long as they perform theintended function. From an accuracy standpoint, it is preferable toinitially bring spindle 20 into the center of ring 32 within an accuracyof only a few thousandths of an inch, say for example, 0.012 inch.

A second collar or clamp 46 is also provided around cylindrical member40 and is provided with a bolt 47 or the like so as to render collar 46adjustable along the length of tubular member 40 in the same manner asdiscussed with respect to collar 42. Collar 46 has a mount 48 associatedtherewith and extending outwardly from one side thereof. A swivel joint50 is provided on mount 48 and receives a rod 51 therethrough. Rod 51 isadjustable with respect to swivel joint 50 so as to be moved up or downtherethrough while retaining the ability to swivel therewith. A dialindicator 60 is received at the end of rod 51 opposite swivel joint 50.Dial indicator 60 is attached to rod 51 by further swivel joint 53.

Referring to FIGS. 1 and 2, the dial indicator 60 is comprised of a base61 having a feeler 62 pivotally secured at one end thereof. A dial face63 is presented at an opposite end of base 61 having indicia 64therearound. An indicator 65 is operatively associated with feeler 62and depending upon a displacement of feeler 62, will deviate from itsnormal position around dial face 63 to provide a reading, indicated byindicia 64 that is proportional to the deflection of feeler 62.

Once spindle 20 has thus been moved to the approximate center of ring 32of traverse rail 30, collar 46 may be moved into position such thatfeeler 62 can be rotated around the internal diameter of ring 32 or theouter diameter of ring 32 to indicate both the amount of deviation thatspindle 20 is from the exact center of ring 32 and also the location ofthe deviation. Having noted the deviation on indicator 60, the spindleis tapped in the appropriate direction to be place in the exact centerof ring 32.

In some cases, to maintain spindle 20 at the exact center of ring 32, itis necessary to shim spindle 20 in a particular direction. The shimmingis accomplished by the use of a precision paper or the like to achievethe desired positioning of spindle 20. After spindle 20 has beenappropriately located both perpendicular to traverse rail 30 and withinthe center of ring 32, the spindle support system is again tightenedagainst spindle rail 10 and the spindle then remains in its newadjustment.

The spindle plumbing device as shown in FIG. 1 is ideally suited forplumbing a spindle when the spindle is idle. It is oftentimes feltdesirable to adjust the plumb of the spindle when the spindle isrotating which would, of course, more closely duplicate operatingconditions of the apparatus when receiving yarn on a package supportedthereon. As such, a further embodiment of the present invention is shownin FIG. 3 which may be used to plumb a spindle either when idle or whenrotating. In many respects, the embodiment of the present invention asshown in FIG. 3 is quite similar to the embodiment shown in FIG. 1 andnumbers will be preceeded by a 100 suffix for corresponding parts.

FIG. 3 illustrates a spindle 120 that, though not shown, could besimilarly supported in the manner as shown in FIG. 1. The spindle 120has an elongated spindle body 122 which, as was mentioned with respectto FIG. I, normally receives a textile carrier therearound on which yarnis deposited in a uniform manner. An elongated tubular member 140 havinga longitudinal bore 141 therein is positioned around spindle body 122.Bore 141 of elongated cylindrical member 140 has a bearing surfacereceived therein, represented by two bearings 170. Bearings 170 aresecured to tubular member 140 and are disposed along the length of bore141. Referring to FIG. 4, a bearing 170 is shown to have a centralspindle engaging sleeve or race 171 which is separated from bearing 170by a plurality of roller elements 172. Roller elements 172 may be rollerbearings, ball bearings, pin bearings, or the like. If necessary, thrustbearings or the like may be used to secure race 171 in place.

As shown in FIGS. 3 and 4, the spindle body 122 resides snugly withinsleeve 171 of bearing 170. As such, as spindle 120 rotates, the spindlebody 122 likewise rotates along with sleeve 171 around the rollerelements 172 while the elongated element 140 is held stationary. Thebearing surface of the embodiment shown in FIGS. 3 and 4 thus permitsthe device to be utilized on a spindle while the spindle is rotating andas such, to plumb the spindle under conditions most closelyapproximating the actual operating conditions where yarn is beingapplied onto a carrier supported by the spindle. Though two bearings 170are shown to reside within bore 141 of elongated element 140, a singlebearing surface could likewise be provided, the tubular element 171 ofwhich would conform to the shape of the spindle body to snugly receivesame for rotation therewith. Likewise, depending upon the desires of anindividual, any number of bearings could be provided to realize the endresult.

Elongated cylindrical member 140 has attached to an outer side thereofan adjustable stop member 180. Stop member 180 preferably is threaded tobe screwed into the side of elongated member 140 and is comprised of aplurality of telescoping sections 181, 182 and 183. Stop member 180 maythus be extended outwardly from the device of the present invention tothe next adjacent spindle (not shown) when used to plumb a rotatingspindle such that, the plumbing device is held against rotation whilethe spindle rotates therein. A pivotal connection between member andstop member may be desirable which would permit stop member 180 to bemoved for engagement with elements other than an adjacent spindle.

Elongated cylindrical member 140 may further be provided with a spiritlevel in the upper end thereof. Spirit level 190 is secured to elongatedmember 140 and, referring to FIG. 5 is seen to have a clear uppersurface with a circle 191 inscribed thereon. Spirit level 190 is filledpartially with a fluid while leaving an air bubble therein. Hence if aspindle plumb is to be checked after alignment with the device of thepresent invention, a quick glance at the top of the cylindrical member140 will indicate whether the spindle is plumb. If the spindle is plumb,the air bubble 192 will reside in the center of circle 191 that isinscribed on the top of spirit level 190. This feature of the device ofthe present invention is optional and may be used with the embodimentshown in FIG. 1 or FIG. 3 as desired.

The embodiment of the present invention when used for plumbing rotatingspindles has a further feature that may be advantageously employed.Referring to FIG. 3, collars 142 and 146 are shown to each have abearing surface l42 and 146 respectively against elongated cylindricalmember 140, and retainer rings R and R respectively thereunder. Thuscollars 142 and 146 retain their vertical adjustment capability withrespect to member 140 and after being properly positioned, are heldthereat by retainer rings R and R. The bearing surfaces 142' and 146'then permit collars 142 and 146 to rotate around member 140. Hence whenthe device of the present invention is used to plumb a rotating spindle,spindle 120 rotates while member 140 is held against rotation byadjustable stop 180. Collars 142 and 146 when equipped with bearingsurfaces 142' and 146' may also be rotated during plumbing operation.This feature improves the efficiency of plumbing since adjustable stop180 does not have to be moved to rotate the entire device. Further, thebearing equipped collars 142 and 146 may also be employed with thedevice as shown in FIG. 1.

The remaining features of the device as shown in FIG. 3 are like thoseas described with respect to FIG. 1. As such, further elaboration as tothese parts of the device of the present invention will not be made.

Using the device as illustrated in FIG. 3, a spindle 120 may be plumbedby loosening the appropriate apparatus, placing the elongated member 140over the spindle body 122 where the body 122 resides snugly withinbearings 170 and then bringing the first collar 142 into position toinitially adjust the attitude of spindle 120. Thereafter, the indicator160 is appropriately used and rotated on bearing 146 around the ring 132of traverse rail 130 to indicate whether the spindle 120 is disposedwithout the center of ring 132, and if so, the amount of deviation andalso the direction of deviation.

Though the Figures show two adjustable collars around the elongatedmember of the device, one adjustable collar could be provided having theinitial spindle adjustment means and the dial indicator providedthereon. Moreover, though the dial indicator of the type shown in theFigures as preferred, obviously other types of indicators could beprovided to achieve the equal result.

Having described the present invention in detail, it is obvious that oneskilled in the art will be able to make variations and modificationsthereto without departing from the scope of the invention.
